“…Similarly, it has been surmised that the moon may have an impact on the psychological basis of normal and abnormal behaviour resulting in e.g. uicide, parasuicide, fluctuation in consulting rates with general practitioners and in emergency departments [16][17][18][19][20][21][22]. Most of these studies failed to detect any impact of the moon on the parameter investigated.…”

Kein Einfluss der Mondphase auf die Nachblutungsinzidenz nach Schilddrüsenoperationen: Eine Analyse von 26.852 Operationen Zusammenfassung. Grundlagen: Nichtwissenschaftliche Quellen behaupten, dass Operationen, die bei zunehmendem und vor allem bei vollem Mond durchgeführt werden, ein höheres Risiko für postoperative Komplikationen tragen. Ziel war es, in unserem großem Krankengut zu evaluieren, ob der Mondzyklus die Inzidenz an Nachblutungen nach Schilddrüsenoperationen beeinflusste. Methodik: In einer retrospektiven Kohortenstudie wurden alle 424 Patienten mit Revisionsoperation wegen Nachblutung nach Schilddrüsenoperation im Zeitraum von 1979 bis 2005, für die Datum und Zeitpunkt der Erstoperation genau vorlagen, inkludiert. Die Mondphase zum Zeitpunkt des Hautschnittes der Erstoperation wurde mittels eines Internet-basierten Programms berechnet. Ergebnisse: Nachblutungen waren etwas seltener bei abnehmendem Mond (54,7 % bei zunehmendem Mond, 45,3 % bei abnehmendem Mond; p ¼ 0,052). Trägt man jedoch die Inzidenz der Nachblutungen gegenüber den einzelnen Mondtagen auf, wird eine zufällige Fluktuation ersichtlich: Das lineare Regressionsmodell zeigt keinerlei signifikante Korrelationen (r 2 ¼ 0,0046). Schlussfolgerungen: Die Patienten müssen sich im Rahmen der Terminisierung elektiver Operationen keine Sorgen um die Mondphase machen. Schlüsselwörter: Nachblutung, Mondphase, Mond, Schilddrü senoperationen, Chirurgie.Summary. Background: It has been claimed by nonscientific sources that operations carried out at waxing moon are associated with a higher risk of complications. We aimed to evaluate if the lunar cycle influenced the incidence of postoperative haemorrhage (PH) after thyroid surgery in our large database.Methods: We retrospectively evaluated 424 patients requiring surgery for thyroid disease and suffering from PH from the years 1979 to 2006 for whom the precise operation date and hour were known. The lunar phase at the time of skin incision was calculated with an onlinecalculator.Results: PH was somewhat less prevalent in the waning phase (54.7% waxing, 45.3% waning moon; p ¼ 0.052). If the incidence of PH is plotted for each day of the lunar cycle only a random fluctuation was observed: A linear regression does not yield any significant correlation (r 2 ¼ 0.0046).Conclusions: Patients need not worry about the lunar cycle when deciding on elective surgery.

“…Several papers reported associations between the lunar cycle and the frequency of hospital admissions due to various causes: cardiovascular disease [13], acute coronary events [14], gastrointestinal hemorrhage [15] and infectious diarrhea [16]. Lunar phases were also associated with the number of requests for appointment at a thyroid outpatient clinic [17]. On the other hand, a number of studies showed insufficient evidence or no association between various health-related events and the synodic lunar cycle [18][19][20][21][22][23][24].…”

230Main text: 2938 Tables: 4 3 ABSTRACT Objectives: Popular belief holds that the lunar cycle affects human physiology, behavior and health, including sleep. To date, only a few and conflicting analyses have been published about the association between lunar phases and sleep. Our aim was to analyze the relationship between lunar phases and sleep characteristics. Methods:In this retrospective, cross-sectional analysis data from 319 patients who had been referred for sleep study were included. Individuals with apnea-hypopnea index≥15/h were excluded. Sociodemographic parameters were recorded. All participants underwent one-night standard polysomnography. Associations between lunar cycle (new moon, full moon and alternate moon) and sleep parameters were examined in unadjusted and adjusted models.Results: 57% of patients were males. Mean age for men was 45±14 years and 51±12 years for women. 224 persons had their sleep study done during alternate moon, 47 during full moon and 48 during new moon. There were no significant differences regarding age and gender between groups.Full moon was associated with lower sleep efficiency (median(%) [ Conclusion:Our results are consistent with a recent report and the widely held belief that sleep characteristics may be associated with the full moon.

“…Associations between lunar cycles and health conditions, however, such as increased phone call rates by females to a crisis-call centre, higher frequency in misbehaviors in institutionalized patients, greater behavioral deterioration in patients with schizophrenia, increased occurrence in gout attacks, and higher frequencies in the number of appointment requests in thyroid outpatients; rates of gastrointestinal bleeding; multiparae delivery rates; and numbers of births, have been reported [16-23]. …”

Are patient falls in the hospital associated with lunar cycles? A retrospective observational study

et al. 2005

View full text Add to dashboard Cite

Background: Falls and associated negative outcomes in hospitalized patients are of significant concerns. The etiology of hospital inpatient falls is multifactorial, including both intrinsic and extrinsic factors. Anecdotes from clinical practice exist in which health care professionals express the idea that the number of patient falls increases during times of full moon. The aim of this study was to examine in-hospital patient fall rates and their associations with days of the week, months, seasons and lunar cycles.
