@description: Normalizes a value that is a choice of timing-valued types to an equivalent interval
@comment: Normalizes a choice type of DateTime, Quanitty, Interval<DateTime>, or Interval<Quantity> types
to an equivalent interval. This selection of choice types is a superset of the majority of choice types that are used as possible
representations for timing-valued elements in QICore, allowing this function to be used across any resource.
The input can be provided as a DateTime, Quantity, Interval<DateTime> or Interval<Quantity>.
The intent of this function is to provide a clear and concise mechanism to treat single
elements that have multiple possible representations as intervals so that logic doesn't have to account
for the variability. More complex calculations (such as medication request period or dispense period
calculation) need specific guidance and consideration. That guidance may make use of this function, but
the focus of this function is on single element calculations where the semantics are unambiguous.
If the input is a DateTime, the result a DateTime Interval beginning and ending on that DateTime.
If the input is a Quantity, the quantity is expected to be a calendar-duration interpreted as an Age,
and the result is a DateTime Interval beginning on the Date the patient turned that age and ending immediately before one year later.
If the input is a DateTime Interval, the result is the input.
If the input is a Quantity Interval, the quantities are expected to be calendar-durations interpreted as an Age, and the result
is a DateTime Interval beginning on the date the patient turned the age given as the start of the quantity interval, and ending
immediately before one year later than the date the patient turned the age given as the end of the quantity interval.
If the input is a Timing, an error will be thrown indicating that Timing calculations are not implemented. Any other input will reslt in a null DateTime Interval

Calculates Medication Period for a given MedicationDispense
MedicationDispense instances provided to this function are expected
to conform to the [TODO: MMEMedicationDispense](http://build.fhir.org/ig/cqframework/opioid-mme-r4/StructureDefinition-mmemedicationdispense.html)
profile, which expects:
* 1 and only 1 dosageInstruction, multiple dosageInstruction elements will result in an error
* 1 and only 1 doseAndRate, multiple doseAndRate elements will result in an error
* 1 timing with 1 repeat, missing timing or repeat elements will result in a null
* frequency, frequencyMax, defaulting to 1
* period, periodUnit, defaulting to 1 'd'
* timeOfDay
* doseQuantity or doseRange, missing doseQuantity and doseRange will result in a null
* whenHandedOver or whenPrepared, if missing both whenHandedOver and whenPrepared will result in a null
Note that MedicationDispense status is not considered by this calculation, as the
list of MedicationDispense instances provided to this function should already have
considered appropriate statuses, depending on the use case, typically `completed`,
especially since whenHandedOver would be expected to be present for a completed
MedicationDispense.
Note also that the dosage information recorded in a dispense is expected to be a copy of the
dispense information from the related medication request. As such, the boundsPeriod would be expected
to cover the entire range, and should _not_ be used for timing of the event.
There is also active discussion in the Pharmacy WG about what date should be used if whenPrepared/whenHandedOver is not present.
This may take the form of an "original creation date", but may also be a "status change date" for dispense events that are updating
status of an existing dispense. That discussion is ongoing, so until that is resolved, this logic will return
null if whenPrepared/whenHandedOver are not available.

  "rationale": "Depression affects over 17 million adults in the U.S. (NIMH, 2021) and is estimated to affect nearly a quarter of adults in their lifetime (Burcusa & Iacono, 2007). Symptoms of depression include disturbances in appetite and sleep, anxiety, decreased concentration, and suicidal ideation (NAMI, 2017; Charbonneau et al., 2005). When left untreated, depression can have a dramatic effect on one’s quality of life, causing constant feelings of hopelessness, loss of interest in daily activities and in some cases suicidal ideation (SAMHSA, 2014).\n\nThe American Psychiatric Association (APA) recommends use of antidepressant medication and behavioral therapies, such as psychotherapy, for the treatment and management of depression (APA, 2010). For the past 60 years, antidepressant medication has proven to be effective, especially for patients with more severe symptoms (Fournier et al., 2010). However, studies analyzing adherence to antidepressant medications found that prevalence of nonadherence was high, ranging from 13 percent to 55.7 percent (Sansone, 2012). \n\nClinical guidelines for depression emphasize the importance of effective clinical management in increasing patients’ medication compliance, monitoring treatment effectiveness, and identifying and managing side effects. If pharmacological treatment is initiated, appropriate dosing and continuation of therapy through the acute and continuation phases decrease recurrence of symptoms. Thus, the evaluation of the duration of pharmacological treatment serves as an important indicator in understanding patient compliance with establishing and maintaining an effective medication regimen.",
  "clinicalRecommendationStatement": "American Psychological Association (2019): \n- \"For initial treatment of adult patients with depression, the panel recommends the following in the context of sharing decision-making with the patient when considering options: \n1. That clinicians offer either psychotherapy or second-generation antidepressant.\n2. If considering combined treatment, the panel recommends cognitive-behavioral therapy or interpersonal psychotherapy plus a second-generation antidepressant.”\n\t\n- “For initial treatment of older adult patients with depression, the panel recommends the following in the context of shared decision-making with the patient: \n1. Either group life review treatment or Group Cognitive Behavioral Therapy (either alone or added to usual care) over no treatment \n2. Combined pharmacotherapy and interpersonal psychotherapy (IPT) over IPT alone. Of note, while the study upon which this is based used nortriptyline, the panel recommends a second-generation antidepressant due to the reduced risk of side effects.”\n\nAmerican Psychiatric Association (2010): \n- “An antidepressant medication is recommended as an initial treatment choice for patients with mild to moderate major depressive disorder [I: Recommended with substantial clinical confidence] and definitely should be provided for those with severe major depressive disorder unless electroconvulsive therapy (ECT) is planned [I: Recommended with substantial clinical confidence].” \n\n- \"Patients should be given a realistic notion of what can be expected during the different phases of treatment, including the likely time course of symptom response and the importance of adherence for successful treatment and prophylaxis [I].\"\n\n- \"During the acute phase of treatment, patients should be carefully and systematically monitored on a regular basis to assess their response to pharmacotherapy, identify the emergence of side effects (e.g., gastrointestinal symptoms, sedation, insomnia, activation, changes in weight, and cardiovascular, neurological, anticholinergic, or sexual side effects), and assess patient safety [I].\"\n\n- “During the continuation phase of treatment, the patient should be carefully monitored for signs of possible relapse [I: Recommended with substantial clinical confidence]. Systematic assessment of symptoms, side effects, adherence, and functional status is essential [I: Recommended with substantial clinical confidence], and may be facilitated through the use of clinician- and/or patient-administered rating scales [II: Recommended with moderate clinical confidence]. To reduce the risk of relapse, patients who have been treated successfully with antidepressant medications in the acute phase should continue treatment with these agents for 4–9 months [I: Recommended with substantial clinical confidence].”\n\nDepartment of Veterans Affairs, and Health Affairs, Department of Defense (2022): \n- “For patients with major depressive disorder (MDD), we suggest using a quantitative measure of depression severity in the initial treatment planning and to monitor treatment progress at regular intervals to guide shared treatment decision making.” [Weak For]\n\t\n- “In patients with MDD who achieve remission with antidepressant medication, we recommend continuation of antidepressants at the therapeutic dose for at least six months to decrease risk of relapse.” [Strong For]\n\nDepartment of Veterans Affairs, and Health Affairs, Department of Defense (2016):\n- ”In patients at high risk for recurrent depressive episodes and who are treated with pharmacotherapy, we recommend offering maintenance pharmacotherapy for at least 12 months and possibly indefinitely.” [Strong For] \n \n- “After initiation of therapy or a change in treatment, we recommend monitoring patients at least monthly until the patient achieves remission. At minimum, assessments should include a measure of symptoms, adherence to medication and psychotherapy, and emergence of adverse effects.” [Strong For] \n\n- “In patients with MDD who achieve remission with antidepressant medication, we recommend continuation of antidepressants at the therapeutic dose for at least six months to decrease risk of relapse.” [Strong For]",
